Reaction Steps

To 50 ml of methanol add 1.0 g (2.93 mmole) of 4-[(methylsulfonyl)amino]-N-[2-(thiomorpholin-4-yl)ethyl]benzamide. Add dropwise 3.08 ml (3.08 mmole) of 1.0N hydrochloric acid. Cool the solution to 0° C. Slowly add 0.70 ml (6.16 mmole) of 30% w/v hydrogen peroxide. Stir the reaction at ambient temperature. Monitor the progress of the reaction by thin layer chromatography on silica gel (methanol:1M NaCl; 95:5). Upon the completion of the reaction, add 25 ml of 10% sodium sulfite to the stirring solution. Filter the resulting solid. Evaporate the filtrate in vacuo to yield a solid. Stir this solid in H2O overnight, then filter the solid and recrystallize it from methanol to yield the title compound.
